Tough to say for sure since I can't see the actual rim, but I wouldn't worry about it. It is odd though that the pressure went down. If it holds overnight should be ok, just take it easy.
that's about the degree of ouchies I have on a set of rims that have been fine for the last 10 years.
Not a big deal to get straightened out once home if you are concerned.
